On Clean Monday (Kathara Deftera), the peaceful nautical town of Galaxidi transforms into a true battlefield filled with colour, laughter, and music. It is the day of the traditional custom of the Alevromoutzouromata (Flour-Smudging), a “battle” where the streets, the walls, and, of course, the participants are covered in tons of flour, soot (foumo), and coloured powders. The celebration culminates at the port, creating a spectacular cloud that momentarily hides the sun, offering a unique display of absolute revelry.
